PAD-INKED HAND STAMPWITH STENCIL'ATTACHING MEANS Filed Feb. 17, 1964 INVENTOR. CARL E. CARLSEN I A TTOR/VE'Y United States Patent M 3,298,304 PAD-INKEI) HAND STAMP WITH STENCIL- ATTACHING MEANS Carl E. Carlsen, 867 3rd Ave., New York, NY. 10022 Filed Feb. 17, 1964, Ser. No. 345,506 2v Claims. (Cl. 101125) This invention relates to new and useful improvements in hand stamps, and it has for its object to provide, what may be termed a miniature stamp, which, while combining all the essential features of my Patents Nos. 3,101,048 and 3,103,879, at the same time adds new features, especially in the simplicity of manufacturing, by, for instance, introducing an inner ink storage pad and a printing pad sewn together in the form of a sleeve adapted for easy attachment to a perforated printing cylinder by just being pulled over the latter.

The said printing cylinder has in this connection been reduced to an inexpensive part, which adapts itself to be renewed together with the two pads as a unit, and permits easy renewal of said pads.

Further, these two pads will completely cover all four sides of the .printing cylinder, thereby preventing this from damaging a stencil.

As the outer edges of the pads are not being squeezed, no ink will escape at their sides, nor will any ink escape at the beginning and finishing of the printing motion, because of the edges which features insure a clean stamp.

Still further, this stamp has a handle bent back upon itself, which is especially useful for a small stamp, because it is inexpensive and it permits said handle to be gripped by the whole hand.

In addition, this stamp has a stencil and a stencil attaching arrangement whereby the actual printing space remains large in proportion to the stamp, and no matter how small the stamp may be, the stencil will always be so large that it may conveniently be held in a typewriter; furthermore, this stamp simply applies a pull to the stencil suitable to a small stamp, which obviously is particularly essential.

Thus, another object of the invention is to make a small stamp, using an inexpensive easily renewable pad for accommodation of the user, who wishes to select his own ink, such as colored or quick drying inks, which would require constant renewal of the pad; thus a suitable ink may be sold together with the stamp, which will keep the pads fresh in regular use, while at the same time the working features of the stamp are similar to the revolving machines.

The stamp may be used to produce identical printing, which would require constant renewal of the pads, like the machines.

In the accompanying drawings, forming part of this application, the number reference numerals indicate corresponding parts in all views, and in which:

FIGURE 1 is an exploded view in perspective of my invention.

FIGURE 2 is a perspective view of a unimeograph stencil.

FIGURE 3 is a perspective view of the invention in operable condition.

FIGURE 4 is an elevational end view of FIGURE 3.

Referring now to the drawings, and particularly to FIGURES 1 and 3 the reference numeral indicates the upper part of the stamp, which may be bent back upon itself to form a handle 11. The stamp is provided with a bottom part 12 which has the general shape of a semi-cylinder.

The said bottom part 12 is at its both ends, provided with cut-aways 13-13. The upper part 10 of 3,298,304 Patented Jan. 17, 1967 the stamp is formed with projecting edges 14-14 on each side thereof, and it has at its top Surface two or more solid prongs 15, 15 adapted to engage openings 15a, 15a in a stencil 20.

A resilient member 16 is arranged below the upper part 10 to which it has one end secured as at 17, while the other end of the member 16 projects through an opening 13 and terminates in a relatively rigid member 19-19 adapted to engage openings 19a, 19a in the stencil 20. The springy member 16 and flexible member 1919 are of unitary construction.

A small part of edge 14 is cut away to show springy member 16.

The pads consist of two parts, an inner ink storage pad 28, and an outer printing pad 29 between which the perforated printing cylinder 25 is inserted, said pads being sewn together at their edges as at 30.

The printing cylinder 25 is formed with perforations 26, which force the distribution of the ink and provide a sharp clear printing, equal to that of a revolving machine. The printing cylinder has at each corner, projections 27, adapted to enage the cut-aways 1313, whereby to attach said printing cylinder 25 to the bottom part or semi-cylinder 12 in a removable manner; the projections 27 may be bent back upon themselves in order to secure the engagement of said parts, as seen at 27a.

The stencil 20 may be provided with printed lines 24, which serve as a guide during the preparation of the stencil by a typewriter, stylus or suitable ballpoint pen.

A regular backing sheet 21 is used in connection with the stencil 20 and is attached at both ends to the latter and is removable from said stencil by means of perforations 22, 22. The numeral 23 indicates a special reenforcement of the stencil 'with paper thinner than that of the regular backing sheet 21 and it extends close to the actual printing space 24 permitting the stamp to be manipulated freely on its sides without smudging the paper that is being printed upon.

The said backing sheet 21 serves to support the actual stencil 20, when this is being prepared. This arrangement is especially desirable and useful, when said actual stencil is prepared by a stylus or a ballpoint pen.

The ink may he applied with a brush to the printing pad before the stencil is attached.

The pad 29 is of a kind commonly used in the revolving machines for supplying ink to the stencil, and rests upon said pad so that when the stamp is used in a rolling motion the ink is forced out through the cutouts in the stencil and on to the paper in the regularway.

The two pads, which may be of different materials, are sewed together at their edges, as at 30, in a long continuous sleeve-like operation, whereupon they may be cut to the desired sizes.

The perforated printing pad or cylinder 25 may be reduced to an inexpensive part, and made so as to be inserted between the two pads. The perforated printing pad 25 has its corners bent so as to grip on to the inner semi-cylinder 12 thereby securing itself and the two pads in an easily removable position, as shown at 27a. It may be seen with this structural arrangement that the printing cylinder 25 and the semi-cylinder 12 are releasably attached one to the other so that interchanging of parts may be affected with a minimum of effort.

I claim as my invention:

1. A miniature hand stamp comprising an upper part bent upon itself to form a handle and having an opening therein, a bottom part having the shape of a semi-cylinder and being connectable to said upper part, said bottom part being formed at both ends with cut-aways, a plurality of projecting edges disposed on each side of said upper part, a pair of prongs at the top surface of the stamp, a resilient member having one end thereof secured underneath said upper part in a cantilever manner and having its other end extending toward said opening in said upper part, said other end of said resilient member being provided with and terminating in a relatively rigid member, said relatively rigid member extending upwardly through said opening in said upper part, and a stencil having openings therein on each of its sides, the openings on one side being connectable to said pair of prongs at the top surface of said upper part, said openings on the other side of said stencil being connectable to said relatively rigid member thereby clamping said stencil to said upper part.

2. The miniature hand stamp according to claim 1 being provided with an inner ink storage pad and an outer printing pad sewn together to provide a unitary member, said unitary member being provided with a perforated printing cylinder disposed between said inner ink storage pad and said outer printing pad, a plurality of projections disposed on said perforated printing cylinder cooperating with the cut-aways in said bottom thereby holding said unitary member to said bottom part.
